Specification of Letters Patent.

Patented Nov. 28, 1905,

Application filed February 25, 1904.. Serial No. 195.237.

To all whom it may concern:

Be it known that I, ELISI-IA E. LATHROP, a citizen of the United States, residing at Hartford, in the county of Hartford and the State of Connecticut, have invented a new and useful Combination-Lock, of which the following is a specification.

This invention relates especially to a combination-lock designed for use with handbags, suit-cases, trunks, and other similar receptacles, and I have shown same applied to a hand-bag or grip of the usual construction.

The object 0 this invention is to produce a keyless lock manipulated by reverse movements of a pointer over a dial, thereby avoiding the necessity of carrying a key to open the hand-bag or grip with; and it will be understood that while the combination for any particular lock is fixed it may vary over a wide range for different locks of the same construction, and the combination adapted to open the lock secured on any particular hand-bag would be known to the maker and purchaser, but unknown to any one having ut' temporary possession of it.

The invention consists of the novel features of construction and combination of parts hereinafter described, articularly pointed out in the claims, and s own in the accompanying drawings, in which Figure 1 is a perspective view showing the practical application of my invention. Fig. 2 is a vertical transverse section through the lock-casing. Fig. 3 is a vertical elevation of the inner side of the front plate of the casing, the attached parts being shown in elevation. Fig. 4 is a vertical transverse section through the lock-casing adjacent an end of the casing. Fi 5 is a face view of the casing, showing the ial in elevation. Fig. 6 is a section on the line 6 6 of Fig. 2. Fig. 7 is a section on the line 7 7 of Fig. 2. Fi 8 is a section on the line 8 8 of Fig. 6, and Fig. 9 is a vertical section on the line 9 9 of Fig. 2. Fig. 10 is a perspective view of the locking-block.

In the drawings, A represents a valise, grip, or hand-bag adapted to open longitudinally along the top, the meeting edges overlapping in the usual manner. The casing B, containing the locking mechanism, is carried by one side of the hand-bag and contains the sliding bolts B, which are adapted to engage the keepers B carried by the opposite side of the bag and adapted to penetrate the inner side of the case and project into the paths of the bolts and at right angles to the bolts, the keepers being a ertured, and suitable coilsprings B are a apted to draw the bolts B into engagement with the apertures of the keeper, and it will be obvious that as long as the bolts B are in such engagement the two sides of the bag are securely locked together. The bolts B carry vertical studs B, which project upwardly and outwardly through the top of the casing and are ada ted to slide in slots (not shown) in the or inary manner, and'by forcing the studs along the slots in opposite directions the bolts B will be disengaged from the keepers and the bag may then be opened. As the movement of the studs B toward each other will result in releasing the keepers and unlocking the bag, the following described device is intended to prevent such movement by unauthorized persons by interposing a locking-block between the bolts, preventing what will be termed their inward movement, and to provide means whereby the owner of the bag may cause the locking-block to fall below the plane of the bolts when it is desired to unlock the bag and to force the block back to locking position after the bag has been relocked, it being understood that when the bag is closed the springs B will automatically throw the bolts into engagement with the keepers and lock the bag and that the locking-block is to prevent unlocking of the bag by forcing the studs B together.

Between the side plates of the casing B, I arrange a U -.shaped plate A, which forms the bottom and ends of the casing and in-' closes on three sides the working mechanism, the bolts B workin horizontally throu h apertures in the memher A and adjacent t e top of the casing B. In the casing B and extending transversely throu h the same is journaled a shaft C, having wlthin the casing an intermediate squared portion C .Upon the outer face of the casing B, I arrange a dial C having a circular scale laid off onits face. The outer end portion of the shaft C passes loosely through the center of the dial, and rigidly secured to the shaft is a pointer (f adapted to travel over the scale when the shaft is rotated, and a knob C is formed on the outer end of the shaft 0, by means of which the shaft may be rotated in either direction. the casin I arrange loose disks E ha gri EBEST AVAlLABLE COP Each of these disks is portion of the shaft.

On the formed with a peripheral slot E squared portion C of the shaft C are fixed vious that when the shaft C is rotated to theright one of the disks only will be rotated. As shown in the drawings, the disk E will be rotated by rotation of the shaft C to the right and disk E by rotation of the shaft C to the left. I also provide a pear-shaped cam G, secured adjacent its apex upon the squared portion C of the shaft C between the two cams F.

The locking-block H has squared ends and is ada ted to fit .snu ly between the inner ends 0 the bolts B w en they are in proper engagement with the keepers B The block H as a downward extension H arranged on the under side of the block and along its longitudinal axis, and this extension is adapted to rest between the disks E and E and serves a to guide the block in its vertical movement.

On each side of this extension H are transversely-arranged webs H at right an gles to the block and adapted to engage the slots of'the disks. The extension H is curved on. its under face and midway the ends of the block projects below the lower ed e of the webs H i the cam G further rotated and the disks E direct the movements of the block H and to prevent lateral movement of the block, pins J are secured to the top of the casing A and project downwardly into sockets'formed in the top of the block H, the block sliding vertically on the pins, and s rings J encircle the pins and bear downwardl y upon the block H, aiding in holding it firmly in its proper position and in seating the webs in the slots E It will also be noted that the block cannot fall into its lower position below the plane of the bolts B until the two slots are registered and brought simultaneously into alinement with the webs, as the throwing of but one slot E into alinement with one web would leave the remaining web seated on the pehery of the disk whose slot had not been alinement with its coacting +hat the pointer .C,

' d on the shaft C, rotation of the said shaft will not change the relative arrangement of the parts just named.

The operation of the device is as follows, assuming the parts to be in the position shown in Fig. 6, the bag being locked: The pointer C is f xed on the shaft, so that when the shaft C is rotated to the right, which will rotate the disk E, the slot E formed in the disk E, will be brou ht immediately below the alining web H" of the block H when the pointer C* has reached a certain number on the dial-as, for example, 10. When the pointer reaches 1 O, movement to the right is sto ped. During this rotation the pawl F of t e disk E has been slipping upon its cam 4 F and the disk E has not rotated. The pointer C is also fixed with reference to the cam actuating the disk E, and when the disk E has been brought into the position above described by movement of the pointer to the right as far as the numeral 10 on the dial movement is reversed and the shaft rotated to the left, for example, until the pointer reaches the numeral 50, this rotation to the left rotating the diskE but not the disk E. As soon as the pointer C, traveling to the left, reaches the numeral i 50 the slot E of the disk E will be brought into register with the slot E of the disk E and also in alinement with its web H and the slots being below and alining with their respective webs the block H, actingunder ravity and the tension of the springs J, will fall from between the bolts B the webs seating themselves in the slots E The bag can then be unlocked in the usual manner by pressing the studs B toward each other. When the bag has been closed and relocked and it is desired to lock the bolts B against withdrawal from the keepers B the shaft C is rotated in either direction, and the pear-shaped cam G will strike the curved under surface of'the block H and lift same upward into position between the bolts, and as soon as the webs have cleared the slots E one of the diskswhich, depending on the direction of rotation of the shaft Cwill also rotate, taking its slot E from alinement with the web, and by a reverse rotation the other disk is rotated so that the slot formed in it will be out of alinement with the web adapted to engage it.

It will be obvious that in order to permit of the rotation of the shaft C when the webs are in engagement with the slots E as no matter which direction was chosen for the rotation of the shaft one of the pawls F would BEST AVAILABLE coP;

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
